PIM BSR Candidate
This window is used to view and configure the PIM BSR candidate settings. This feature only takes effect
when the interface has an IP address configured and is in the PIM sparse mode.
This feature causes the router to send bootstrap messages to announce the IP address of the designated
interface as the CBSR address. The hash mask is used by all routers within a domain, to map a group to
one of the Rendezvous Points (RP) from the matching set of group-range-to-RP maps (this set all have
the same longest mask length and same highest priority). The algorithm takes as an input the group
Description
Select to enable or disable the PIM passive feature here. When the
passive mode is enabled, the interface will neither send PIM messages
out nor accept PIM messages from this interface. The router will act as
if it is the only PIM router on the network. Use this feature only when
there is only one PIM router on the LAN.
Enter the interval at which hello messages are sent here. The range is
from 1 to 18724 seconds. A PIMv2 router learns PIM neighbors via the
PIM hello message. This feature configures the frequency of the hello
message. Routers configured for IP multicasting send PIM hello
messages to detect PIM routers. For SM, hello messages also
determine the router to act as the designated router for each LAN
segment. The configured query interval is also used as the value for
hold time. By configuring a smaller period for the interval, the
unresponsive neighbor can be discovered faster and thus the failover
and recovery will become more efficient. Select the Default option to
use the default value, which is 30 seconds.
After selecting to use the Sparse Mode or the Sparse-Dense Mode,
this parameter will be available. Enter the Designated Router's (DR)
priority value here. The range is from 0 to 4294967295. A larger value
represents the higher priority. In the Dense Mode (DM), the DR priority
option will not be carried in the hello message. The router with the
highest priority value will be the DR. If multiple routers are with the
same priority status, the router with the highest IP address will be the
DR. If there is a router that does not support the DR priority in its hello
message on the LAN, all routers on the LAN will ignore DR priority and
only use IP address to elect DR. Select the Default option to use the
default value, which is 1.
After selecting to use the Sparse Mode or the Sparse-Dense Mode,
this parameter will be available. Enter the Join/Prune message interval
value here. The range is from 1 to 18000 seconds. When configuring
the Join/Prune interval, consider the factors, such as the configured
bandwidth and expected average number of multicast route entries for
the attached network or link. For the Sparse Mode (SM), routers will
periodically send join messages based on this interval. The hold-time
in a Join/Prune message is 3.5 times the join-prune-interval. The
receiving router will start a timer based on this hold-time, and prune
the interface if no join message was received on this interface. Select
the Default option to use the default value, which is 60 seconds.
Select to enable or disable the Bootstrap Router (BSR) domain border
feature here. The feature only takes effect when the interface is PIM
enabled. Use this feature on the interface that border with another
domain to avoid the exchange of BSR messages across two domains.
